Part One: Knowing the Law and Considerations for Owner/Builder Permit

Understanding the Law

In accordance with Chapter 489, Section 489.103(7)(a) of the Florida Statutes, homeowners are granted an exemption from contracting regulations when acting as their own contractor for specific activities. Specifically, this exemption applies when homeowners are involved in the installation, uninstallation, or replacement of solar panels on one-family, two-family, or three-family residences. It’s important to note that this exemption is applicable only if the local permitting agency’s county or municipal government is participating in a “United States Department of Energy SunShot Initiative: Rooftop Solar Challenge” grant.

However, there are limitations to this exemption. While homeowners can oversee all aspects of the work not performed by licensed contractors, including the installation of solar panels, they must engage a licensed electrical contractor to handle the wiring of the solar panels. This includes any necessary interconnection to the customer’s residential electrical wiring. The specific conditions and limitations of this exemption should be explicitly stated in the building permit approved and issued by the permitting agency for the solar project.

In essence, this provision allows Florida homeowners to take an active role in the solar installation process on their residences. Still, it mandates the involvement of a licensed electrical contractor to ensure the proper and safe wiring of the solar panels, in alignment with state regulations.
